11. A 50.0-g superball traveling at 25.0 m/s bounces off a brick wall and rebounds at 22.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.50 ms, what is the magnitude of the average acceleration of the ball during this time interval?
Remember as the superball rebounds due to the brick wall. It makes the superball go in the opposite direction from where initially was heading at. That's why the minus sign of 25m/s.
